Significats de β decay en anglès

This is the first observation of a two-body baryonic B decay.

We exclusively reconstruct the companion B decay to suppress background.

Signal events are selected by examining the properties of the system recoiling against either a reconstructed hadronic or semileptonic charged- B decay.

The results provide both qualitative and quantitative new insights into CP -violation effects in hadronic B decays.

The analysis uses events in which the signal B decays are reconstructed with an innovative loose neutrino reconstruction technique.

We also report improved measurements of the momentum distributions of psi produced directly from B decays, correcting for measurement smearing.

We present updated measurements of time-dependent CP asymmetries in fully-reconstructed neutral B decays to several CP eigenstates containing a charmonium meson.

From the spectrum, we observe Omega(c)(0) production from B decays and in cc events, and extract the two rates of production.

These channels are of interest to study the mechanisms behind hadronic B decays, and open new possibilities for CP violation analyses with larger data sets.

CP-violation parameters for each of the three modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays.
